+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You

+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+

+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.

+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+ThinkPHP 5.0 Workerman 扩展
+===============
+
+## 安装
+composer require topthink/think-worker
+
+## 使用方法
+首先创建控制器类并继承 think\worker\Server，然后设置属性和添加回调方法
+
+~~~
+namespace app\index\controller;
+
+use think\worker\Server;
+
+class Worker extends Server
+{
+	protected $socket = 'http://0.0.0.0:2346';
+
+	public function onMessage($connection,$data)
+	{
+		$connection->send(json_encode($data));
+	}
+}
+~~~
+支持workerman所有的回调方法定义（回调方法必须是public类型）
+
+
+在应用根目录增加入口文件 server.php
+
+~~~
+#!/usr/bin/env php
+<?php
+define('APP_PATH', __DIR__ . '/application/');
+
+define('BIND_MODULE','index/Worker');
+
+// 加载框架引导文件
+require __DIR__ . '/thinkphp/start.php';
+~~~
+
+在命令行启动服务端
+~~~
+php server.php start
+~~~
+
+
+linux下面可以支持下面指令
+~~~
+php server.php start|stop|status|restart|reload
+~~~
+
+在浏览器中进行客户端测试
+http://127.0.0.1:2346/?id=1

+## What is it
+Workerman is an asynchronous event-driven PHP framework with high performance to build fast and scalable network applications. 
+Workerman supports HTTP, Websocket, SSL and other custom protocols. 
+Workerman supports libevent/event extension, [HHVM](https://github.com/facebook/hhvm) , [ReactPHP](https://github.com/reactphp/react).
+
+## Requires
+PHP 5.3 or Higher  
+A POSIX compatible operating system (Linux, OSX, BSD)  
+POSIX and PCNTL extensions required   
+Event extension recommended for better performance  
+
+## Installation
+
+```
+composer require workerman/workerman
+```
+
+## Basic Usage
+
+### A websocket server 
+```php
+<?php
+require_once __DIR__ . '/vendor/autoload.php';
+use Workerman\Worker;
+
+// Create a Websocket server
+$ws_worker = new Worker("websocket://0.0.0.0:2346");
+
+// 4 processes
+$ws_worker->count = 4;
+
+// Emitted when new connection come
+$ws_worker->onConnect = function($connection)
+{
+    echo "New connection\n";
+ };
+
+// Emitted when data received
+$ws_worker->onMessage = function($connection, $data)
+{
+    // Send hello $data
+    $connection->send('hello ' . $data);
+};
+
+// Emitted when connection closed
+$ws_worker->onClose = function($connection)
+{
+    echo "Connection closed\n";
+};
+
+// Run worker
+Worker::runAll();
+```
+
+### An http server
+```php
+require_once __DIR__ . '/vendor/autoload.php';
+use Workerman\Worker;
+
+// #### http worker ####
+$http_worker = new Worker("http://0.0.0.0:2345");
+
+// 4 processes
+$http_worker->count = 4;
+
+// Emitted when data received
+$http_worker->onMessage = function($connection, $data)
+{
+    // $_GET, $_POST, $_COOKIE, $_SESSION, $_SERVER, $_FILES are available
+    var_dump($_GET, $_POST, $_COOKIE, $_SESSION, $_SERVER, $_FILES);
+    // send data to client
+    $connection->send("hello world \n");
+};
+
+// run all workers
+Worker::runAll();
+```
+
+### A WebServer
+```php
+require_once __DIR__ . '/vendor/autoload.php';
+use Workerman\WebServer;
+use Workerman\Worker;
+
+// WebServer
+$web = new WebServer("http://0.0.0.0:80");
+
+// 4 processes
+$web->count = 4;
+
+// Set the root of domains
+$web->addRoot('www.your_domain.com', '/your/path/Web');
+$web->addRoot('www.another_domain.com', '/another/path/Web');
+// run all workers
+Worker::runAll();
+```
+
+### A tcp server
+```php
+require_once __DIR__ . '/vendor/autoload.php';
+use Workerman\Worker;
+
+// #### create socket and listen 1234 port ####
+$tcp_worker = new Worker("tcp://0.0.0.0:1234");
+
+// 4 processes
+$tcp_worker->count = 4;
+
+// Emitted when new connection come
+$tcp_worker->onConnect = function($connection)
+{
+    echo "New Connection\n";
+};
+
+// Emitted when data received
+$tcp_worker->onMessage = function($connection, $data)
+{
+    // send data to client
+    $connection->send("hello $data \n");
+};
+
+// Emitted when new connection come
+$tcp_worker->onClose = function($connection)
+{
+    echo "Connection closed\n";
+};
+
+Worker::runAll();
+```
+
+### Enable SSL
+```php
+<?php
+require_once __DIR__ . '/vendor/autoload.php';
+use Workerman\Worker;
+
+// SSL context.
+$context = array(
+    'ssl' => array(

+    )
+);
+
+// Create a Websocket server with ssl context.
+$ws_worker = new Worker("websocket://0.0.0.0:2346", $context);
+
+// Enable SSL. WebSocket+SSL means that Secure WebSocket (wss://). 
+// The similar approaches for Https etc.
+$ws_worker->transport = 'ssl';
+
+$ws_worker->onMessage = function($connection, $data)
+{
+    // Send hello $data
+    $connection->send('hello ' . $data);
+};
+
+Worker::runAll();
+```
+
+### Custom protocol
+Protocols/MyTextProtocol.php
+```php
